How long is the appointment of the director as agent for service of process valid?

The appointment of the director as an agent for service of process is valid for as long as there could be a cause of action against the licensee. This means that, regardless of any specific time frame, the appointment remains active as long as there are potential legal claims or issues that could arise related to the actions of the licensee.

This ensures that legal processes can be appropriately served without the need for reappointment or renewal at regular intervals, providing a consistent method for addressing any liability related to the conduct of the licensee. This principle helps to streamline legal proceedings and offers protection to the public, as it guarantees that there is always a point of contact for legal processes associated with the licensee's actions during the effective period of their license.

The other options propose fixed time frames or conditions that do not align with the reality of ongoing legal liabilities, making them less suitable in this context.
